Whether the non-super high speed transmission circuit 204 is turned on. Then, since the ultra high speed transmission circuit 202 is turned off, the USB peripheral device 208 decides to use the non-super high speed transmission circuit 214 and the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200 for data transmission. In addition, after the ultra-high speed transmission circuit 202 is turned off, when the data transmission amount between the USB 3.0 main control device 200 and the USB peripheral device 208 is again greater than a preset value, or the data transmission between the USB 3.0 main control device 200 and the USB peripheral device 208 When the amount is again greater than the preset value and the switching loss is in compliance with the power management policy, the control module 206 re-opens the ultra-high speed transmission circuit 202 and sends a reset signal to the USB peripheral device 208. However, when the data transmission amount between the USB 3.0 main control device 200 and the USB peripheral device 208 is again greater than a preset value and the switching transmission loss does not comply with the power management policy, the control module 206 does not restart the ultra high speed transmission circuit 202, and does not A reset signal will be sent to the USB peripheral device 208. When the USB peripheral device 208 receives the reset signal, the USB peripheral device 208 first detects whether the ultra-high-speed transmission circuit 202 of the USB 3.0 main control device 200 is turned on according to the specification of USB 3.0, and then detects the USB 3.0 main control device 200.

The method of FIG. 4 is illustrated by the USB 3.0 main control device 200 and the USB peripheral device 208 of FIG. 3A. The detailed steps are as follows: Step 400: Start; Step 402: Connect the USB peripheral device 208 to the USB 3.0 main control device 200; 404: The control module 206 controls the ultra high speed transmission circuit 202 of the USB 3.0 main control device 200 to connect with the ultra high speed transmission circuit 212 of the USB peripheral device 208, and turns off the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200; 406: The control module 206 determines whether the data transmission amount between the USB 3.0 main control device 200 and the USB peripheral device 208 is greater than a preset value; if yes, proceed to step 408; if not, skip to step 410; step 408: control module 206 controls the super high speed transmission circuit 202 of the USB 3.0 main control device 200 to perform data transmission with the USB peripheral device 208, and jumps back to step 406; Step 410: The control module 206 first turns on the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200. And the ultra high speed transmission circuit 202 is turned off, and the non-super high speed transmission circuit 204 and the non-super high speed transmission circuit 214 of the USB peripheral device 208 are controlled to perform data transmission, and the process returns to step 406.
在步驟402中，USB週邊裝置208係為USB 3.0週邊裝置。在 步驟404中，當USB 3.0主控制裝置200與USB週邊裝置208間初始連接時，控制模組206根據USB 3.0的規範，控制超高速傳輸電路202與USB週邊裝置208的超高速傳輸電路212進行連接並關閉USB 3.0主控制裝置200的非超高速傳輸電路204，其中超高速傳輸電路202係用以第一傳輸速度傳送資料。在步驟408中，當USB 3.0主控制裝置200與USB週邊裝置208間之資料傳輸的量大於預設值時，控制模組206控制USB 3.0主控制裝置200的超高速傳輸電路202與USB週邊裝置208的超高速傳輸電路212進行資料傳輸，並關閉USB 3.0主控制裝置200的非超高速傳輸電路204。在步驟410中，當USB 3.0主控制裝置200與USB週邊裝置208間之資料傳輸的量小於或等於預設值時，控制模組206先開啟USB 3.0主控制裝置200的非超高速傳輸電路204以及關閉超高速傳輸電路202，並控制USB 3.0主控制裝置200的非超高速傳輸電路204與USB週邊裝置208的非超高速傳輸電路214進行資料傳輸。而USB 3.0主控制裝置200的非超高速傳輸電路204係用以第二傳輸速度(高速傳輸電路2042)、第三傳輸速度(全速傳輸電路2044)或第四傳輸速度(低速傳輸電路2046)傳送資料，其中超高速傳輸電路202的第一傳輸速度係高於第二傳輸速度、第三傳輸速度與四傳輸速度。另外，在步驟410中，當控制模組206關閉超高速傳輸電路202並開啟非超高速傳輸電路204時，控制模組206亦可發出一重置訊號至USB週邊裝置208。當USB週邊裝置208接收到重置訊號時，USB週邊裝置208根據USB 3.0的規範，先偵測USB 3.0主控制裝置200的超高速傳輸電路202是否開啟，再偵測USB 3.0主控制裝置200的 非超高速傳輸電路204是否開啟。然後，因為超高速傳輸電路202係為關閉，所以USB週邊裝置208決定利用非超高速傳輸電路214和USB 3.0主控制裝置200的非超高速傳輸電路204進行資料傳輸。另外，在步驟406和408中，在關閉超高速傳輸電路202後，當USB 3.0主控制裝置200與USB週邊裝置208間之資料傳輸量再度大於預設值時，控制模組206重新開啟超高速傳輸電路202，並發出重置訊號至USB週邊裝置208。當USB週邊裝置208接收到重置訊號時，USB週邊裝置208根據USB 3.0的規範，先偵測USB 3.0主控制裝置200的超高速傳輸電路202是否開啟，再偵測USB 3.0主控制裝置200的非超高速傳輸電路204是否開啟。然後，因為超高速傳輸電路202係為開啟，所以USB週邊裝置208決定利用超高速傳輸電路212和USB 3.0主控制裝置200的超高速傳輸電路202進行資料傳輸，且控制模組206再度關閉非超高速傳輸電路204。In step 402, the USB peripheral device 208 is a USB 3.0 peripheral device. in In step 404, when the USB 3.0 main control device 200 and the USB peripheral device 208 are initially connected, the control module 206 controls the ultra high speed transmission circuit 202 to connect with the ultra high speed transmission circuit 212 of the USB peripheral device 208 according to the specification of USB 3.0. And the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200 is turned off, wherein the ultra high speed transmission circuit 202 transmits the data at the first transmission speed. In step 408, when the amount of data transmission between the USB 3.0 main control device 200 and the USB peripheral device 208 is greater than a preset value, the control module 206 controls the ultra-high speed transmission circuit 202 and the USB peripheral device of the USB 3.0 main control device 200. The ultra high speed transmission circuit 212 of 208 performs data transmission and turns off the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200. In step 410, when the amount of data transmission between the USB 3.0 main control device 200 and the USB peripheral device 208 is less than or equal to a preset value, the control module 206 first turns on the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200. And the ultra high speed transmission circuit 202 is turned off, and the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200 and the non-super high speed transmission circuit 214 of the USB peripheral device 208 are controlled for data transmission. The non-super high speed transmission circuit 204 of the USB 3.0 main control device 200 is used for transmitting the second transmission speed (high speed transmission circuit 2042), the third transmission speed (full speed transmission circuit 2044), or the fourth transmission speed (low speed transmission circuit 2046). The data, wherein the first transmission speed of the ultra high speed transmission circuit 202 is higher than the second transmission speed, the third transmission speed, and the fourth transmission speed. In addition, in step 410, when the control module 206 turns off the ultra high speed transmission circuit 202 and turns on the non-super high speed transmission circuit 204, the control module 206 can also send a reset signal to the USB peripheral device 208. When the USB peripheral device 208 receives the reset signal, the USB peripheral device 208 first detects whether the ultra-high-speed transmission circuit 202 of the USB 3.0 main control device 200 is turned on according to the specification of USB 3.0, and then detects the USB 3.0 main control device 200. Whether the non-super high speed transmission circuit 204 is turned on. Then, since the ultra high speed transmission circuit 202 is turned off, the USB peripheral device 208 decides to use the non-super high speed transmission circuit 214 and the non-super high speed transmission circuit 204 of the USB 3.0 main control device 200 for data transmission. In addition, in steps 406 and 408, after the ultra-high speed transmission circuit 202 is turned off, when the data transmission amount between the USB 3.0 main control device 200 and the USB peripheral device 208 is again greater than a preset value, the control module 206 re-turns the ultra-high speed. The circuit 202 is transmitted and a reset signal is sent to the USB peripheral device 208. When the USB peripheral device 208 receives the reset signal, the USB peripheral device 208 first detects whether the ultra-high-speed transmission circuit 202 of the USB 3.0 main control device 200 is turned on according to the specification of USB 3.0, and then detects the USB 3.0 main control device 200. Whether the non-super high speed transmission circuit 204 is turned on. Then, since the ultra high speed transmission circuit 202 is turned on, the USB peripheral device 208 decides to use the ultra high speed transmission circuit 212 and the ultra high speed transmission circuit 202 of the USB 3.0 main control device 200 for data transmission, and the control module 206 turns off the non-super High speed transmission circuit 204.
